这样就提交请求，并且获取请求结果了。

一般返回的结果是json格式的。

 

第二种方式：

复制代码
　　/**
     * 模拟post进行url请求
     * @param string $url
     * @param array $post_data
     */
    function request_post($url = '', $post_data = array()) {
        if (empty($url) || empty($post_data)) {
            return false;
        }
        
        $o = "";
        foreach ( $post_data as $k => $v ) 
        { 
            $o.= "$k=" . urlencode( $v ). "&" ;
        }
        $post_data = substr($o,0,-1);

        $postUrl = $url;
        $curlPost = $post_data;
        $ch = curl_init();//初始化curl
        curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页
        curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
        curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
        curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
        $data = curl_exec($ch);//运行curl
        curl_close($ch);
        
        return $data;
    }
复制代码
将拼接也封装了起来，这样调用的时候就更简洁了。

复制代码
function testAction(){
        $url = 'http://mobile.jschina.com.cn/jschina/register.php';
        $post_data['appid']       = '10';
        $post_data['appkey']      = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';
        $post_data['member_name'] = 'zsjs124';
        $post_data['password']    = '123456';
        $post_data['email']    = 'zsjs124@126.com';
        //$post_data = array();
        $res = $this->request_post($url, $post_data);       
        print_r($res);

    }

不使用curl提交：

$data = array(
	'foo'=>'bar', 
	'baz'=>'boom', 
	'site'=>'www.lai18.com', 
	'name'=>'lai18'); 
	
$data = http_build_query($data); 
// $data="foo=".$data['foo']."&baz=". $data['baz']."&site=".$data['site']."&name=".$data['name'];
//$postdata = http_build_query($data);
$options = array(
	'http' => array(
		'method' => 'POST',
		'header' => 'Content-type:application/x-www-form-urlencoded',
		'content' => $data
		//'timeout' => 60 * 60 // 超时时间（单位:s）
	)
);
 
$url = "http://www.lai18.net/";
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
 
echo $result;
